HENRY P. ENGELN, OF CLEVELAND, OHIO, ASSIGNOR TO THE H. P. ENGELN COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

MASSAGE-PUMP.

Specification of Letters Patent.

Patented m. 27, 1906.

To all whom it may concern:

Be it known that I, HENRY P. ENGELN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Massage-Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to a device adapted for massage treatment, and more especially adapted for individual use.

The objects of my invention are its convenience for individual use, comprising its adaptability to be secured and operated by the individual requiring or desiring treatment and to be secured at any convenient place.

Another object of my invention is to provide a simple device which will not become inoperative or require mechanical skill to adjust or operate or assemble the parts after the device has once left the factory.

IVith the above objects in view my invention consists in providing a compact structure integral as to its supporting-standard and adjustable clamping mechanism and it further consists in the supporting of the airpump upon a swivel-joint in such a manner that the pump-cylinder can be turned or will turn upon itself, according to the requij ed direction, without manual interference ij 'rs required during the massage operation}? My invention further consists in thpeculiar construction of the device whereby it is adapted for the erformance above set forth, all of which will e hereinafter fully set forth and claimed.

In the drawings, Figure I is a view in side elevation of my device, illustrating the internal construction of the pump, which is shown in vertical section. Fig. II is a view in rear elevation, illustrating the pump with the parts assembled and the relation of the parts to each other.

This device is intended for the use of the individual desiring treatment and is intended and constructed so that it can be operated by the person without any assistance, both as regards the convenience of its position and the operative parts of the device. In this fact resides the practical value of the device, and to attain this object the device is prefer ably constructed as follows:

A represents a standard havin at its upper end a journal or bearing B, 1n which is mounted a shaft B, supporting and controlling the movements of a crank-wheel C, and an operating device or rotating device D, which is preferably in the form of a balancewheel with a handle I) attached. A pitman E is secured to a wrist-pin e on the crankwheel C. This pitman in turn is connected to a iston F, which reciprocates in a cylinder the said piston and cylinder constituting the air-pump.

I preferably form the cylinder and its ports in one piece, although this is not essential, and the valves controlling the ports may be so constructed (see Fig. I) as to cause suction at the connection g or to cause pressure, this feature being immaterial as regards the pump. By forming the base of the cylinder G heavy, as illustrated in Fig. I, it allows of placing it directly in connection with aswivelsupport J. This swivel-support J allows of the rocking of the cylinder by means of its pivotal connection, as at j, which allows the cylinder to oscillate, as required by the throw incident to the revolution of the crank-wheel C and its wrist-pin or arm 6; but as in some cases it is necessary that the cylinder G, or more especially the connection 9, should be located according to the line of the tubing attached thereto, thus obviating the kinking of the tube and shutting off of the action resultant from the operation of the pump, I have located the swivel J central in the bottom of the cylinder G, preferably providing screw-threads upon the upper end of swivel J and in the aperture in the bottom of the cylinder into which the swivel is entered, allowing the cylinder G to turn u on the swivel connection and oscillate in a iorizontal direction,accommodating the connection to the direction of the hose. (Illustrated in dotted lines in Fig. I.) The swivel connection J is illustrated as a loosely-fitting threaded screw, which threaded screw is centrally located and engages within the base of the pump in such a manner as to allow of the orizontal oscillating motion on said swivel.

The swivel J isprovided at its lower end with a collara', which is pivoted upon a'pin j in the base A" at right [angles to the swivel J to allow of movement of the cylinder in a plane at an angle toitsplane of rotation.

From the base A of the standard A, I eX- tend an arm A downward and another arm A horizontally or at right angles thereto, and in the arm A at its free end I provide an internal screw-thread engaged by a clampingscrew K. The parts A, A A and K=form a clamp integral with the standard and its base,* whereby the device may bepositioned at convenience for -instance at the edge of the table, a dresseryor shelfnorotherconvenient and like article. Itwill-be'seen that the "clamping-screwKis centrally located in vertical-axial linewith the pump and'its'be'aring at the :base, thus: allowing the clamp to adhere-firmly to' a narrow ledge and allowing edge as far as relatesto the clamping of the machine inpos'ition. This enablesthe device *first"; to be portable sec'ond,'to be operated by the person desiring themassage treatm'ent,

and-," thirdly-, the who le structure is compact,

convenient, simple, positively operative, and

requires no adjustment beyond thescopeof knowledgeof any ordinary educated individual.

1 In s'etting' forth this invention Ih'ave illustrated and described certain details of con- =stru'ction andoperation of parts which may be modified'without'departingfrom my invention.

"What I claim is 1 A deviceof the type set forth comprising a standard, surmounted bya crankwheel, an air-pump operated by means of said crank-wheel, said air-pump being mounted upon the base of the standard by swivel connection, which allows. it to. oscillate in both a vertical and horizontal direction.

I 2. A'device ofthe type set forth, com rising a standard surmounted by a crank-w eel, an air-pump-operatedby said crank-wheel, a

= swivel connecting the=pump and the base of the staridardysaid swivelbeing connected to the base by a pivotal connection, whereby {the pivot may be: oscillated with respectto the base.

A device 'of the type=set forth-,"com rising a standard surmounted-by a crank-w eel,

an -air pump operated by'said crank-wheel, a

swivel-pin entered 1 into Y the bottom of*- the pump upon whichthe pumpmayrotate, the

other end of-said'swivel being provided with a collar pivoted upon a pin' at right angles to the swivel,;wher'eby the pump=may have an oscillatory motion at right angles to its" aforesaid rotary motion.
